@clara@EzraMungai those specs look fine. I don't see any memory issues, though our production servers generally have 56Gb RAM or more. Requirements would depend on your usage and number of users submitting data etc. It's not an easy calculation unfortunately. There has apparently been an update to the MALT task in a newer build, so deploying the latest might solve the issue. See here:
Clearing the MALT task in the mean time as per the firefighting instructions may sort it out until the next monthly run.
